Endocrine Review for CCRN Exam Cram

Flashcards covering key concepts from the endocrine review notes, focusing on SIADH, diabetes insipidus, DKA, and HHS.

Syndrome of Inappropriate Antidiuretic Hormone Secretion (SIADH)

Condition characterized by excessive secretion of ADH leading to water retention, concentrated urine, decreased urine output, and diluted serum sodium.

Urine Concentration

The measure of solute concentration in urine, which is high in conditions like SIADH and low in Diabetes Insipidus.

Hyponatremia

A condition where serum sodium levels are low, often a complication of SIADH due to dilution of blood.

Dilantin

A medication used to inhibit ADH secretion in the treatment of SIADH.

Diabetes Insipidus

Condition caused by insufficient ADH secretion, leading to excessive urination and increased serum sodium.

Vasopressin

A synthetic form of ADH used in the treatment of Diabetes Insipidus.

Diabetic Ketoacidosis (DKA)

A severe complication of diabetes characterized by high blood sugar (>250 mg/dL), rapid development, ketone production, and low insulin.

Hyperglycemic Hyperosmolar Syndrome (HHS)

A serious condition more common in older adults associated with extremely high blood sugar (>600 mg/dL) and dehydration, without significant insulin deficiency.

Kussmaul Breathing

A pattern of rapid, deep breathing associated with metabolic acidosis, particularly seen in DKA.

Serum Osmolality

A measure of solute concentration in the blood, critical for differentiating between DKA and HHS.

Hypoglycemia

A condition characterized by abnormally low blood sugar levels, where beta blockers may mask symptoms, leading to decreased level of consciousness.
